Yes actually! I originally fixed it by putting little dots of silicone between the housing and the glass, but that eventually came away too during the really hot days so I looked into it a bit more... there’s actually just a little holder thing which it slides into to hold it too the glass but it’s impossible to see with the housing in the way. All you have to do is hold the housing against the glass in the position it looks it should sit it in, then slide it up to the towards roof!
Quick Edit: Sorry read your post properly and on mine it was just the plastic housing bit which came away from the metal back! I would try some quality superglue? Or some of that gorilla tape?
